METHOD OF AND APPARATUS FOR SATURATING'I'APER.

' Application filed May 10,

To all whom it may concern:

Be it known that I, CHARLES A. CooNEY, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Methods of and Apparatus for saturating Paper, of which the follow ing is a specification.

In saturating paper with such material as asphalt it is difiicult to maintain the asphalt at a sufliciently high temperature to assure its ready absorption by the paper. Where the asphalt chills the absorption immediately becomes slower and consequently the rapidity with which the paper may be saturated is correspondingly reduced. To obviate this difficulty it has been common to supply auxiliary heating means for the heating tank but inasmuch as the asphalt must be maintained at a high temperature such supplemental heating is very difiicult.

Another method employed has been to return the asphalt to the still or heating tanks and re-heat it.

By reducing the spacein the'saturating tank so that there is a correspondingly small amount of saturating material in the tank the material may be taken up with such rapidity by the paper as to assure a use of the material so shortly after its introduction into the saturating tank that its initial tem erature may be very nearly maintained. nde'r these conditions the material is absorbed very rapidly by the paper so that the paper may be run through it with much greater rapidity and the taking off of the material with the paper consumes a correspondingly shorter period. Therefore the period of time from the introduction of the material to the tank until it'is removed by the paper is such as to prevent any material cooling in the tank.

The invention involves a simplified apparatus for carrying out 'the'method as well as the method.

The apparatus is illustrated in the accompanying drawings as follows Figure 1 shows a section on the line l-1 in Fig. 2. f,

1 marks the saturating tank. It has an inlet opening 2 which leads to a discharge valve 3, the discharge valve being controlled by a valve disk 4 carried by a lever 5. The lever 5 is mounted on a bracket 6 extending from Specification of Letters Patent.

the inlet pipe 2. A float 7 is secured to the lever 5. This device operates in the usual manner. Vhen the liquid operates on the float it closes the valve 4 but when the level of liquidis reduced the valve is opened. A frame 8 is secured to the top of the tank. It has the side beains 9. Paper 10 is led into the tank over a roll 11, the roll being carried by a shaft 12 journaled in the side beams 9 (the journals not being shown). The paper is carried from the roll 11 vertically down through the tank around a roll 13 at the bottom of the tank and then by alternate passes over a series of rolls 14 at the top and rolls 13 atthe bottom.- The paper is carried out of the tank between the rolls 15. These rolls are carried by a shaft 16 and the shafts are journaled in bearings 17 carried by the side frames 9. The rolls 14 are mounted on the shafts 18 and the shafts are carried in bearings 19 in the side frames 9. The rolls 13 are mounted on the shafts 20 and these shafts are carried by the lift bars 22. The lift bars are provided with the guide ribs 23 which operate in guides 24 extending upwardly from the sides 9. The lift bars are provided with the racks 25 and pinions 26 mesh with these racks. The pinions are mounted on shafts 27, said shafts having squared ends and the shaft are mounted in brackets 28 on the guides 24. A crank 29 is adapted to fit on the squared ends of the shafts 27 and by means of it the lift bars may be raised carrying the rolls 13 into alinement with the rolls in the machine. Dogs 30 are provided for looking the rack bars in their upper position.

The pinions and shafts27 operating on the rack bars at each side act as a paralleling mechanism so as to assure a free running of the lift bars.

In order to reduce the space occupied by the saturating material in the tank I fill a large portion of the tank 'with displacing elements 31 and 32 ordinarily in the form of closed tanks. The elements 31 are mounted between the guide bars and are lifted out of the tank with the rolls 13. There are a series of elements 32 occupying the space between the elements 31 so' that the paper has a pass between these elements that is quite confined.

With this construction the passage of the paper is in vertical lines and parallel so that the tank is very much reduced in size as compared with-the common prac tice so that the volume of materials in the tank is correspondingly reduced and l the time period between the introduction into the paper and its entrance to the tank is very short as compared with the methods now in use for saturatingpaper. In consequence the volume of product is very much increased with a single unit and at the same time the space required for the unit is very much decreased. One of the principal advantages of this method and structure arising from the comparatively short period that elapses between the introduction of the material and its absorption by the paper is the higher temperature possible to be maintained in the material so that rapid saturation of the aper is made possible. All the features, t erefore, work in harmony in permitting of greater speed and more perfect saturation.

What I claim as new is 1. The method of saturating paper which consists in rapidly passing the, paper through a saturating material and delivering said saturating material at a high temperature into absorbing relation to the paper while confining the space occupied by the saturating material after it is placed. in absorbing relation to effect a rapid transfer of the material from the point of delivery into saturating relation to the paper.

2. The method of saturating paper which consists in rapidly passing the paper through a saturating material in confined ways and delivering said saturating material at a high temperature into absorbing relation to the paper. while confining the space occupied by the saturating material after it is placedin absorbing relation to effect a rapid transfer of the material from the point of delivery into saturating relation to the paper.

3. In a saturating apparatus, the combination of a tank; rollers at different levels for guiding paper into and out of the tank; devices for delivering saturating material to the tank; and means for reducing the space within the body of the tank and through which the paper passes.

4. In a saturating apparatus, the combination of a tank; rollers at different levels for guiding'paper into and out of the tank; devices for delivering saturating material to the tank; and means for reducing the positioned to lead the paper in a series of paths through the tank; fillers between the paths; and means for raising the lower rollers from the tank.

7 In a saturating apparatus, the combination of a tank; a series of upper rollers; a series of lower rollers, said rollers being positioned to lead the paper in a series of paths through the tank; fillers between the paths, and means for raising the lower rollers and fillers from the tank with the fillers above said lower rollers.

8. In a saturating apparatus, the combi nation of a tank; a series of upper rollers; a series of lower rollers positioned to lead the paper in a series of paths through the tank; a series of stationary fillers below the upper rollers; means for raising the lower rollers; and a series of fillers above the lower rollers, said last-mentioned fillers being movable with the lower rollers.

9. Ina saturating apparatus, the combination of atank; an upper series of rollers mounted at the upper part of the tank; a lower series of rollers; lift bars carrying said lower rollers; guides for said lift bars; means acting on the lift bars for raising the lowerrollers; and fillers arranged between the lift bars and movable with the lower rollers.

10. In a saturating'apparatus, the combination of a tank; a series of upper rollers; a series of lower rollers, said rollers forming a series of paths for paper passing over them; a float arranged between two of the paths; and an inlet valve controlled by the float.

11. In a saturating apparatus, the combi nation of a tank; a series of rollers at the upper part of the tank; a series of rollers at the lower part of the tank, said rollers beingpositioned to form vertical parallel paths of the paper led from one series of rollers to the other series: and fillers between the paths confining the paper to confined spaces between the fillers.

In testimony whereof I have hereunto set my hand.

CHARLES A. OOONEY.
